Welcome to our March 2015 Issue of our CoolStuff Newsletter. This month, we are featuring a simple, safe and Cool device called an Energy Stick. Physics teacher James Lincoln demonstrates several experiments that help students understand the principles of electric current and light. James has authored many of our past CoolStuff Newsletters, and teachers [...]

10 thermal conductivity demos for less than $12
Watch Physics Teacher James Lincoln use the simple, inexpensive Liquid Crystal Sheet to visually demonstrate:
-the temperatures of varying light sources
-how styrofoam insulation works
-the wavelength of a microwave
-plus much more!

Check out how MLB can use a thermal energy camera to determine whether a hit ball is foul or live. Then watch Dr. Baseball use the more budget friendly colliding steel spheres to create some thermal energy of his own.

Watch how silly putty and simple steel spheres can be used to demonstrate the conversion of kinetic energy into thermal energy! (And you thought Silly Putty was for copying comics from the newspaper!)

I have been using tuning forks in my classroom for 10 years, and in each of those years I have discovered several new tricks. I hope you can learn many of these from this publication. For a more complete treatment and my references, please see my article in “The Physics Teacher” March, 2013.

What can you do with a plasma ball? We get this question a lot! Check out these simple, cool demos using everyday lab items like fluorescent lamps, LEDs, neon gas tubes, and even your own body! You’ll be amazed at how easy and fun teaching and learning about electrostatics can be.

It was 8:45 AM in Florence and I was waiting for one of the highlights of my 2012 Italian family vacation the chance to see the original creations for one of the greatest minds of the 17th century, Galileo. Take a tour of the Galileo Museum with me and see the classic Physics demos as they were in the 1600's.

Think back to when you were a little kid playing one of your most enjoyable family games on Saturday night. It involved rolling a die and moving around a game board, all while building a complex “mousetrap”, hoping that you wouldn’t get caught in its devious shenanigans or secretly wishing that its numerous “Energy Transfers” would fail to work!

Whether we realize it or not, all velocity/speed measurements are made relative to some other object. When your car's speedometer reads 55 mph, the assumption is that the change in position of the car compared to the stationary ground is 55 miles every hour. However, not all velocity/speed measurements are made relative to a stationary object. The Constant Velocity cars allow students to experimentally investigate relative speeds as the cars with different speeds move in the same and in opposite directions.
